4090/4080 eDP DP_D vBIOS MOD

I made a vBIOS mod for RTX 4090/4080 based on the 4070 MXM card. There's a 99% chance it won't work due to falcon but who knows??

 

Anyways simply put, 4070 has eDP on DP_D whereas 4080/4090 has eDP on DP_B.

 

I simply modified the DCB table to match the 4070. 

 

WARNING: nvflashk will probably say invalid ROM. You will need to flash using SPI programmer.

Thanks.

 

But What, so their datasheet were right??? It said eDP on B I was like no way...

 

I have the datasheet of the RTX 4060 and it says eDP on D.

 

I don't have them with me right now.

 

X-Vsion answers about DP_D issue:

 

We encountered a factory with H610 motherboards that had this phenomenon, but later the BIOS PCIE was set to ASMP Disabled and they could be used 

 

MSI B760M-P open UEFI and CSM OK

 

Z690 no

 

Asrock B550 open UEFI and CSM OK

 

ASUS H610 Some models work, some models don't

 

I also sent them your Google drive link so they can test it and maybe... Find someone to certificate them?
